ACR CAPT REPORTS RADIO INTERFERENCE ON INTERCOM DURING PUSH BACK AT SEA.

Narrative

BEFORE PUSHBACK I COULD HEAR THE HANDLER WELL OVER THE INTERPHONE. HOWEVER ONCE PUSHED BACK FROM NORTH SATELLITE; I COULD NOT DISTINGUISH WHAT THE GROUND HANDLER WAS SAYING OVER THE INTERPHONE DUE TO INTERFERENCE FROM WHAT SOUNDED LIKE A COMMERCIAL RADIO STATION. I WAS EVENTUALLY ABLE TO HEAR ENOUGH TO MAKE EDUCATED GUESSES ON THE PROGRESS ON THE GROUND HANDLER; AND WE STARTED ENGINES AND I RELEASED HIM. HAD THERE BEEN ANY UNUSUAL SITUATIONS; WE WOULD NOT HAVE BEEN ABLE TO COMMUNICATE. I OFTEN HEAR AN INTERFERENCE LIKE THIS (SOUNDING LIKE A COMMERCIAL RADIO STATION) IN THIS LOCATION IN SEA. USUALLY IT IS WEAK ENOUGH TO HEAR OVER; BUT NOT THIS TIME. I HAVE WRITTEN UP THIS SITUATION BEFORE. IN THIS CASE; THE SEVERITY MAY HAVE BEEN AIRCRAFT RELATED; BUT THE CONTINUAL OCCURRENCE IS LOCATION RELATED.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE REPORTER COULD ADD NO ADDITIONAL INFORMATION EXCEPT TO SAY THAT THE INTERFERENCE WAS DEFINITELY COMING THROUGH THE INTERCOM SINCE NO OTHER COMMUNICATIONS SOURCES WERE SELECTED AT THE TIME.
